We want to reproduce some of the characteristics that make difficult the life in Mars. Among them we can have the air pressure between 7 and 10 mbar, the gases composition, the high temperature range going from -70ºC to 20ºC in some parts of the planet. Once we achieve this humble goal, we can use the chamber to try our engineered yeasts with the LEA gene and observe its behavior: if it grows, just only survives without growing or dies. It’s a very important part of the project because is an easy way to prove whether the yeast can grow or at least survive in an environment with such limitations as Martian atmosphere can be.
